The body snatchers.

The creature pulled out a large needle and jabbed it into Jamie's arm, as Jamie winced and whined the creature began to extract Jamie's blood. When it was done, the strange being walked away into the darkness as it illuminated to reveal a large machine. The alein's grey twin walked to the other side of her table and used some sort of small laser to heal her arm. The first little grey man stuck the needle containing Jamie's blood into a hole in the machine and began emptying her blood into the hole. After all the blood sample was all within the machine, it pressed a button that activated what ever function this device preformed. Jamie lay their confused and scared, she wondered what the machine could do and what her captors would do to her after it finished.

A few minutes pass before the machine appears to be finished and out of the side a door opens releasing steam into the room. Jamie looked on in horror as she saw herself exit the machine and walke over to the alein that had brought it to life. Jamie's imposter had every last tiny detail of her appearance, her large breasts topped off by two stiff perky nipples, her long saplely legs stemming from her gorgeous ass, the butterfly tattoo on her hip, the cute little mole on her cheek, she even walked like Jamie with the same sway her her ass performed thanks to each step taken by her legs. Then it spoke. "Hello, #2637. Your name will be Xilla and your mission is to infiltrate Earth society and learn as much as you can," said the bulb headed creature using what appeared to be telepathy. The imposter responded verbally, "As you command sir," as the alein walked back over to Jamie. "We'll continue with our speciemen while you begin you mission," it "said" while its twin pressed a button that turned Jamie's table into a hovering slab with her still on it. The grey men guided the hovering slab into another room as the imposter walked to the center of the original room of the spacecraft. Jamie struggled and screamed all the way into the other room where she saw strange devices and more aleins.

Xilla could hear Jamie yelling and sounds of devices and probes starting up, getting ready to explore her supple form. When she reached the center of the room, Xilla began to disappear into a bright light. When she reappeared she was on Earth's surface and the sun was rising over the horizon. Xilla was flanked by a brick wall and a chain link fence to her left and right, a green and yellow dumpster behind her, and the corner of the brick wall off to the right in the front. She stood there naked and knowing nothing of Earth or its society, only its speech.
